Designing and optimizing the galvanized quenching and partitioning process: Evolution of microstructure and transformation behavior

Sachin Kumar, E.De Moor, Kyoung Min Kim, Ho Yong Um et autres

This work explores key aspects of designing and optimizing the quenching and partitioning process integrated with galvanizing (GI Q&P) for developing next-generation automotive steels. A conventional CMnSi steel was quenched below the martensite-start temperature, followed by partitioning at 460 °C for time …
